How to install Clojure for emacs?

[slix]

I want to use the emacs mode from Jeffrey Chu.

Where should I install it? in the clojure directory under emacs? then
set a load path to there and that is it?

[Paul Barry]

Here's how I do it using Aquamacs, you can alter this if you are using a different emacs:

0.  Follow instructions at http://en.wikibooks.org/wiki/Clojure_Programming#Installation_from_Source to get clj installed and in your path, verify that it works by running clj from the command line.

1.  mkdir ~/emacs

2.  cd ~/emacs

3a.  If you have git installed, run this:

git clone git://github.com/jochu/clojure-mode.git

3b. If you do not have git installed, download this tarball:

http://github.com/jochu/clojure-mode/tarball/master

And untar it in the ~/emacs directory

4.  Start Aquamacs

5.  C-x C-f ~/emacs/clojure-mode/clojure-mode-config.el (opens up that file for editing)

6.  Enter this:

(provide 'clojure-mode-config)

(setq inferior-lisp-program "clj")

(require 'clojure-mode)

(setq auto-mode-alist

      (cons '("\\.clj$" . clojure-mode)

            auto-mode-alist))

(add-hook 'clojure-mode-hook

          '(lambda ()

             (define-key clojure-mode-map "\C-c\C-e" 'lisp-eval-last-sexp)))

7.  C-x C-s (saves the file)

8.  C-x C-f ~/emacs/my-config.el

9.  Enter this:    

(provide 'my-config)

(add-to-list 'load-path "~/emacs/clojure-mode")

(require 'clojure_mode_config)

10.  C-x C-f ~/Library/Preferences/Aquamacs\ Emacs/customizations.el

11.  Add this:  

(add-to-list 'load-path "~/emacs")

(require 'my-config)

12.  C-x C-s

13.  M-x eval-buffer  (Reads the configuration in, if no errors, everything worked)

14.  C-x C-f ~/foo.clj (opens a new Clojure file)

15.  C-c C-z (starts the REPL)

If you follow the link from clojure.org to the wiki site, you'll see a
section on setting up emacs:

http://en.wikibooks.org/wiki/Clojure_Programming#Editors.2FIDEs

I took a slightly different approach. I created a script that
contained the line to start clojure:

echo "java -cp jline-0.9.91.jar:clojure.jar jline.ConsoleRunner
clojure.lang.Repl" > ~/bin/clojure

Then inside emacs,

M-x set variable inferior-lisp-program "~/bin/clojure"

[Matt Revelle]

Wherever you'd like and basically yes.

For example:
(add-to-list 'load-path "~/src/clojure-extra")
(add-to-list 'load-path "~/src/swank-clojure")
(add-to-list 'load-path "~/src/clojure-mode")

The wiki should have the rest of the info.

But this is just a mode right?

I use a lot of different languages, I dont want to autostart clojure
or anything. just have it as an option.

Having some troubles:

An error has occurred while loading `c:/Users/saftarn/AppData/

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file. Start Emacs with
the `--debug-init' option to view a complete error backtrace.

i changed
(setq load-path (cons "C:/clojure_20080612/Progs/" load-path)) to
C:/emacs-22.2/clojure-mode/

is that correct?

still get:
